WASHING-MACHINE.

Specification of Letters Patent.

Patented June 28, 1910.

Application filed July 28, 1906. Serial No. 328,247.

To all whom it may concern:

Be it known that I, HENRY S. JUDD, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement in Washing-Machines, ofwhich the following is a specification.

My invention relates to washing machines.

The object of my invention is to provide a washing machine efficient inoperation and not liable to get out of order.

My invention consists in a number of features which will be readilyapparent as the specification proceeds.

Referring to the drawings, Figure 1 is a front, Fig. 2 a front centralsectional, Fig. 3 a plan, and Fig. 4 an end central sectional view ofthe device of my invention. Fig. 5 is a front and Fig. 6 a side,partially sectional, detail view of the hook for supporting a spring.Fig. 7 is a sectional side view, and Flg. 8 is a sectional front view ofthe pivotal device for the bottom of the springs. Fig. 9 is a bottomview of the plate on which the device of Figs. 7 and 8 bears. Fig. 10 isa perspective detail view of the knife edge bearing nut of Figs. 7 and8. Fig. 11 is a detail view in elevation of the swinging wringer-boardor block. Fig. 12 is an enlarged fragmentary view in perspective showingthe construction of the gasket employed to prevent leakage between thevessel and its lid or cover. Figs. 13 and 14 are sectional views of thesame illustrating the manner of assembling the parts.

Again referring to the drawings, I provide a washing machine body orvessel, hava front wall 15, rear wall 16, side walls 17 and 18, bottom19 and top 20, of the general type shown in my prior application.Extending from the front and rear walls 15 and 16 are short trunnions 21and 22, journaled in brackets 23 and 24:, which are suitably mountedupon vertical supports or standards 25 and 26. These vertical supportsare rigidly secured to the base of the machine, which consists of frontand rear members 27 and 28 connected together by a central cross-member29.

In order that the operator may give the vessel such motion, I provideupon the top of the device suitable upright supports 85 carrying handles36 adapted to be grasped by one or more persons to facilitate carryingthe machine around. In order to put soiled clothes into the vessel andto retain the water therein during the washing process, hinge to the top20 at 39 a suitable cover 40 adapted to close the opening in the top 20through which clothes may be inserted into the machine, this cover beingnormally held in closed position by the button 11, or other suitabledetachable securing mechanism. For convenience, I provide a handle 42which the operator may grasp to tilt the cover 40 upon its hinges 39, toopen the vessel. In order to insure this cover 10 fitting suflicientlytight in the opening provided for it, so that water within the machinewill not leak out around the edges of the cover during the washingoperation, I provide a special form of gasket which is illustrated indetail in Figs. 12, 13 and 14. This gasket may be upon the edges of thecover itself or upon the inner edges of the top 20 of the vessel, thelatter being the construction illustrated. I run a channel or rabbet 15in the edge of the part which is to have the gasket, and over this I laya strip or preferably two of packing 4a which should be of felt or othersimilar fabric, although rubber might be used. The latter, however, isnot so desirable as it is susceptible to the action of hot-water andsoap, and is apt to rapidly deteriorate. I then lay a strip 15preferably of wire upon the packing and drive both strip and packinghome to a bearing in the channel, where it is subsequently secured bystaples or other fastening devices 46. The packing used is wide enoughso that when in final position, the edges project considerably for thepurpose of crowding against the adjacent surface of the other part ofthe vessel. By this construction there is a double packing, so to speak,one for each edge of the strip and moreover the packing when worn may bereadily removed by merely withdrawing the staples and lifting out theretaining strip. This door 40 is provided with vents or air and steamescape openings 50, and a protecting corrugated plate 51, such as isshown and described in my prior application before referred to.

In order to allow the water within the machine to readily pass throughthe meshes or fabrics of the clothes to thereby mechanically remove thedirt contained in them, I provide within the machine a plurality ofslats 5 1 separated from each other, as shown in Fig. 4, so that thereare spaces 55 between them extending entirely around the interior of themachine. These spaces afford passages for the water which has passedthrough the clothing supported at any point within the machine uponthese slats. In order that the clothing may be held in fixed positionsupon the slats, so that the water may pass through it, I provide theinterior faces of these slats with notches 56 against which the clothingmay engage. Similarly, to hold the clothing in suitable positions uponthe front and rear interior faces of the machine, I provide in saidfront and rear walls suitable corrugations or notches 58, as shown.These slots also direct the flow of water and prevent endwisecirculation which tends to twist the clothing when long articles are inthe machine.

In order to assist the operator in oscillating the machine body orvessel, I secure to one side wall 15 of the machine a suitable casting60 having an arm 61 depending below the bottom of the vessel at theright of the center line A A thereof, and olf-set toward the front framesupport 26, as shown in Fig. 4, and upon the other wall 16 I secure acorresponding casting 63 having an arm 64 depending from the bottom ofthe vessel at a distance to the left of the center line A A equal to thedistance which the said arm 61 is to the right. This arm 64 is, as shownin Fig. 4, off-set toward the rear vertical support 26, an amount equalto the off-set of the arm 61, as heretofore described. The off-sets justdescribed are, as will hereinafter more clearly appear in thedescription of the operation, provided so that the springs controllingthe vessel will entirely clear the vessel as it oscillates. The springsare wholly outside the path of travel of the tub and below the tub.

On the bottom of each depending arm 61 and 64 is a horizontal lug 67, asis best shown in Fig. .6, machined to receive a suitable bushing 68 ofless width than the width of the lug 67, as shown in Fig. 6. Journaledupon this bushing 68 is a hook of the same or slightly less width thansaid bushing and of perceptibly less width than the lug 67. Through thedepending arm lug 67 I secure a rivet or bolt 7 2 adapted to secure awasher 73, in the posit-ion shown in Fig. 6, against lugs 67. Thiswasher is, as shown, of a diameter sufiicient to engage and hold inposition both the bushing 68 and the hook 70, but these latter twomembers being of less width than the lug 67, there is no binding actionby the washer upon them, therefore they are free to rotate upon the lug67 as a pivot. Each hook 70 is provided with a notch 7 5 in which theupper loop 76 of a retractile spring 77 is adapted to rest. The objectin thus providing a special articulate joint and interposing it betweenthe lug 64 and spring 77, is to eliminate the constant bending orworking of the loop which would occur if said loop were hung directlyupon said lug. Ithas been found by experience that such bending orworking does occur when the connection is made direct and results in acrystallizing of the spring and ultimate fracture. With my hook, themovement takes place between the lug and the hook, and as the parts aremachined, the operation is especially smooth and the life of the springis indefinitely prolonged.

By having the arms 61 and 64 off-set at opposite sides of the centraltransverse plane of the machine, as shown, I obtain a tension upon thevessel upon opposite sides of such plane, thereby steadying and stoppingthe vessel in a fixed position; whereas, when the springs are attacheddirectly in the central transverse plane, there is no such steadyingaction.

Extending from the lower end of each spring, 77, is a rod 80, of alength suflicient to reach substantially to the ground, screwthreaded inits lower end 81 for receiving a nut 82 which has upon its upper faceknife edges 83, as best shown in Figs. 7 and 10. The cross-bar 29 of thebase-frame has upon its bottom a metal plate 85 apertured at 87 for thepassage of rods 80,'and having at proper places notches 84, in whichsaid knife edges 83 are adapted to bear. The body of the cross-bar 29has cut therein below each depending arm 61 and 64, U-shaped recesses89, registering with apertures 87 as best shown inFigs. 1, 2, and 8.Rods pass through them to reach the apertures 87, and are adapted tooscillate backward and forward crosswise of the machine, bearing dur ingsaid oscillation upon the knife-edges 83, as described. As heretoforestated, the'arms 61 and 64 are off-set so that the springs 77, entirelyclear the side walls of the machine, so far as interference by thesprings with any part of the vessel is concerned, it may rotate in acircle. In other words, the oscillation of the vessel is not interferedwith by the springs, as is the case with the machine of my priorapplication.

By locating the knife edges 83 at the low est possible point, asdescribed, the machine has a greater length of swing without stretchingthe springs beyond the points to which they would be stretched, werethey mounted higher up. It is desirable that the points of connection ofthe springs to the frame be such that a line through said points ofattachment is parallel to the axisof osoil lation of the vessel. Thisconstruction is best illustrated in Fig. l in which the machine isviewed from the side and the two springs seem to meet at a point.

In order to limit the movement of the vessel and assist in its return tonormal position with the least possible tension upon springs 77 Iprovide bufier blocks 91 carrying buffer springs 92 adapted to beengaged by stop blocks 93, when the machine has been rotated from thefull-line position of Fig. 1 to the dotted line position of that figure.This limits the arc of rotation of the machine to approximately 180.

In order to provide for a wringer which may be used when the machine is,not being oscillated, and may be moved out of the way when the machineis in operation, I hinge at 95, upon the vertical support 25, a plate 96carrying a wringer board or block 97 secured at an angle thereto, therelation of the parts being such that when they are moved from the fullline position of Fig. 4 to the position of Fig. 11, the board 97 is inupright position as there shown (also in dotted lines in Fig. 4) so thata wringer secured to the block 97 is in proper position at the side ofthe machine to be used for the purpose of wringing clothes. Ihis board97 resting upon the top of the machine, as shown, steadies it, so thatit will not oscillate during the wringing operation. In order to insurethis condition, I provide suitable latches 99, best shown in Fig. 4,adapted to engage suitable projections 100 upon the front of the board97, the operator throwing these latches 99 to the position of Fig. 4,when he desires to secure the wringer board 97 to operative position andreleasing the latches when he desires to throw it back out of operativeposition. The operative position is shown in dotted lines Fig. 1 and thenon-operative position in full lines in that figure. In the latterposition it rests upon the bracket 101, out of the way of theoscillating vessel.

It is desirable that when in non-operative position the wringer board beback far enough only to just clear the vessel. From this position theboard with its attached wringer may be thrown back to operative positionwith minimum effort. Said bracket is preferably adjustable so thatwringers of different makes and styles may be accommodated and each onerest when in non operative position back far enough to just clear theoscillating vessel. This adjustment is secured by slotting said bracketand providing a wing nut 101 (see Fig. 11) screwing on to a threadedstud 101 fixed to said vessel and projecting through said slottedbracket.

In order to facilitate the drawing of clothes out of the vessel inoperating the wringer I journal within the machine, and adjacent to theopening in the cover, and adjacent to the base of the wringer when 1noperative position, a suitable roller 105 over which the clothing maypass from the mterior of the vessel to the wringer.

I have shown my machine as equipped to be operated by hand, but, ofcourse, it could be operated by power.

Having thus described my invention what I claim as new and desire tosecure by Letters-Patent is 1. In a washing machine, the combinationwith a supporting-frame and an oscillating vessel pivoted thereto, of aspring having its upper end connected to the oscillating vessel, a rodextending from the lower end of the spring, and a nut upon said rodhaving knife-edges bearing upon said supporting-frame.

2. In mechanism of the class described, the combination with a washingmachine vessel. and its supporting frame, of a lug carried by saidvessel, a bushing mounted upon said lug, a hook journaled upon saidbushing, means for holding said hook and bushing upon said lug whilepermitting free rotation of the hook, and a spring connected to saidhook and to the machine-frame.

3. In a washing machine the combination with a supporting frame and anoscillating vessel pivoted thereto of a hook plvoted to said vessel, aspring suspended from said hook, a rod extending from the lower end ofsaid spring, and a nut upon said rod having knife edges bearing uponsaid supporting frame.

In witness whereof, I have hereunto subscribed my name in the presenceof two witnesses.
